Description

General description

hexane and low boiling point hydrogen treated naphtha

Application

Petroleum ether may be employed in the extraction of biologically active carotenoid pigments from total carotenoid pigments by adsorption.[1] It may be employed in solvent reservoir during the separation of lipid mixtures by adsorption chromatography with silicic acid.[2]
